Open-ZFS For Linux

ZFS – the last word in filesystems ZFS is a new kind of filesystem that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability.
Crossmeta is proud of providing own port of OpenZFS project well optimized for prominent Enterprise Linux 7 with:

Advanced memory optimization by sharing of ARC memory with Linux native page cache, thereby mmap applications will not double-commit memory. This unique feature is available only on our Crossmeta ZFS for Linux.

Well integrated snaphot access in kernel from hidden .snap control directoy, even over NFS, without any helper programs to automount.

Simple package distribution with one kernel module zfs.ko and static CLI tools just the way it was in OpenSolaris.

High performance ZVOL block layer.

Well integrated iSCSI option with our software virtualization engine, so that ZVOL API can be invoked directly from kernel with zero-copy provided by ZFS
